Abstract: 1,207,953. Ornamenting. COLVILLES Ltd. 3 Nov., 1967 [10 Aug., 1966], No. 35872/66. Heading B6G. [Also in Division B2] Fibre flock is deposited on to an adhesivecoated metal sheet 15 from a container 1 provided with electrodes for electrostatically charging the flock, whilst relative reciprocation is effected between the sheet and the container, e.g. by mounting the container on a carriage. The flock may be cotton or synthetic fibre and the adhesive may be polyvinyl chloride-based. The substrate may be a continuous steel sheet, or in the form of steel plates carried on an endless belt. Prior to flocking, the substrate can be cleaned, roughened and primed, adhesive being then applied, e.g. by roller coating, spraying, curtain coating or doctor blade. After fllocking, the adhesive may be cured. As shown, the container 1 includes a rotating brush 3 for directing flock through a sieve floor 4, which with brass strips 5 is connected to a high-tension power source 6, whereby the flock is electrostatically charged. A regainer 8 operates by suction to remove excess flock, and may be connected to the power source 6. Flocking may be assisted by beater bars 16 vibrating the substrate 15. In an alternative embodiment (Fig. 3, not shown), the container comprises a spherical or semicylindrical sieve and is movable by an insulating handle to deposit flock.

Title: Apparatus for Detecting the Wire Mark in Paper
IPC: G01N21/86
Filed: 1966-08-11
Abstract: 1,152,393. Detecting wire marks in paper photo-electrically. INDUSTRIAL NUCLEONICS CORP. Aug.11, 1966 [Aug.11, 1965], No.36042/66. Heading G1A. The wire mark in a web of paper is detected by scanning the web photo-electrically through a mask comprising a plurality of apertures in a pattern corresponding at least partially to the wire mark pattern. The intensity of the wire mark may be measured by applying the detector signal to a high or band pass filter. The signal may also be applied to a low pass filter to indicate larger scale formation of the paper. The spacing of the apertures may be adjusted in accordance with the high pass filter output to maximize the same: the adjusted spacing of the apertures then corresponds to the pitch of the wire mark. The adjustable aperture mask may take the form of diaphragms 54, 56, Fig. 3 connected to plates 22' by loosely bolted rods 65, 66, so that movement of plates 22' perpendicular to the paper movement brings the apertures 50, 52 closer together whilst keeping them mutually parallel. Alternatively the mask 72 may comprise a plurality of diverging slots 74, Fig.4, or diverging wires, Fig.4a (not shown) which co-operate with slot 71 in another mask 70 so that the apparent pitch is variable. Instead of the mask 70, a fixed mask with a number of apertures may be provided, Fig.5 (not shown) each with its own photo-detector and circuitry which selects the detector giving the maximum output. The frequency of the detector output may be measured to give an indication of the web speed and if the dimensions of the wire mark pattern are liable to vary a signal from the part of the apparatus measuring pattern size may be used to correct the speed measurement.

Title: Adhesive priming for anchorage to backing
IPC: C09J7/50
Filed: 1965-08-24
Abstract: A method of producing a pressure sensitive adhesive coated sheet comprises forming a pressure sensitive adhesive film on a supporting surface, priming said pressure sensitive adhesive film by coating the exposed adhesive surface of said adhesive film with a water-based primer which improves the bond between the adheseive and the subsequently applied permanent backing.  Drying said primed adhesive film, and bonding said primed adhesive film to said backing while both are maintained at a temperature of at least 200 DEG F, but substantially below the softening point of said backing to form a laminated structure of adhesive and backing by pressing the primed adhesive film into intimate contact with said permanent backing and then removing said laminate from said supporting surface.  Any conventional pressure sensitive adhesive may be used e.g. natural rubber, such as wild rubber or crepe rubber, synthetic rubber-based adhesives such as styrene/butadiene and butadiene/acrylonitrile co-polymers and polyvinyl acrylate and polyvinyl ether.  The adhesive may be applied by calendering. The support surface may be given a conventional release coating before applying the adhesive coating. The primer may be applied by reverse roll or by doctor blade.  The backing may be an organic film of polyvinyl chloride or of polyvinyl chloride/polyvinyl acetate copolymer.

Title: Improvements in or relating to aircraft
IPC: B64C13/46
Filed: 1954-12-15
Abstract: 780,668. Aircraft feel simulators. HOBSON, Ltd., H. M., WESTBURY, R., and SMITH, C. P. Nov. 23, 1955 [Dec. 15, 1954], No. 36350/54. Class 4. A hydraulic feel simulator for power operated aircraft controls having a hydraulic jack including a piston and housing movable relatively by a linkage operated by the pilot's control against the hydraulic pressure in the housing which increases with airspeed, comprises a spring system for opposing movement of the control member, and means operative while hydraulic pressure prevails in the housing, to displace the spring system to an ineffective position, the system automatically returning to the effective position on failure of the pressure. In one embodiment, Fig. 4, the control column 10 operates the servo system transmitter 13 by a rod 12 pivoted at 16 to a lever 17 pivoted to the aircraft at 18 and to the jack piston rod 20 at 19. The housing 24'is pivoted to a lever 41 at 40 and is attached to a spring 48 anchored to the aircraft. Lever 41 is pivoted to the aircraft at 42, and at its other end to two rods 145 each secured to a pin 144 working in a slot 143 in lever 17. Each pin 144 is attached to a spring 46 anchored to the aircraft at 47. While there is no hydraulic pressure in the housing, spring 48 acts to urge pins 144 to the position shown, where springs 46 act to centre the control column. While hydraulic pressure prevails in the housing, the jack contracts and raises lever 41, placing the pins in the upper ends of slots 143, where they are substantially ineffective. In Fig. 5, the pin 19 engages two slots 50, each in a rod 51 urged outwardly by a spring 54, the two rods and springs constituting a double acting spring box. While there is hydraulic pressure in housing 24, however, pressure fluid supplied by conduits 56 acts on pistons 52 to compress springs 54, whereby the pin 19 moves freely in slots 50 with lost motion. In Fig. 6, a lever 57 has a pin 244 at one end engaging a slot 43 in lever 17. The other end of the lever has a collar 59 acted on by spring 58 and a piston 61 subject to the hydraulic pressure in the housing 24. While the hydraulic pressure prevails, piston 61 is raised and the pin 244 is near pivot 18, whereby spring 58 is substantially ineffective to centre the column 10, If the pressure fails, the pin moves to the position shown, and spring 58 provides centering forces. Specifications 734,437 and 740,510 are referred to.

Title: Process for the production of copolymers
IPC: C08F218/08
Filed: 1955-12-20
Abstract: Vinyl acetate is copolymerized with a secondary or tertiary unsaturated carbamic acid ester of the formula R11-NR111-CO-O-R1 where R1 represents an aliphatic residue with a terminal double bond, R11 an aliphatic, aromatic, cycloaliphatic or heterocyclic residue and R111 a hydrogen atom or residues as R11, by a bulk, emulsion or solution method.  Carbamates of unsaturated alcohols such as allyl alcohol, isopropenyl carbinol, b -ethyl allyl alcohol, and allyl carbinol, which may be obtained by reacting isocyanates with the alcohols or secondary amines with the chloroformic acid esters of the alcohols, may be used.  Catalysts such as hydrogen or benzoyl peroxide, preferably in acid solution, may be employed and in the bulk polymerization the addition of a polymer, particularly polyvinyl acetate increases the rate and lowers the temperature of reaction. In examples, N-phenyl allyl carbamate is copolymerized with vinyl acetate, in bulk, by refluxing with dibenzoyl peroxide catalyst; in solution, to give a pearl polymer by dropwise addition of a solution of phenyl allyl carbamate in vinyl acetate to an aqueous solution of polyvinyl alcohol, sec.-sodium phosphate and hydrogen peroxide; in emulsion by suspending a mixture of phenyl allyl carbamate and vinyl acetate with vigorous stirring in an aqueous solution of high viscosity polyvinyl alcohol, hydrogen peroxide and formic acid. Films, coatings and filaments made from the copolymers have high water-resistance and hardness and the copolymers of the di- and tri-carbamates give insoluble high - melting polymers.

Title: Process for the polymerisation of vinyl chloride and polymeric compositions
IPC: C08F259/04
Filed: 1959-11-03
Abstract: Vinyl chloride polymers having a relatively low degree of polymerization are produced by a process comprising polymerizing monomeric vinyl chloride in the presence of a liquid vinyl chloride polymer.  The vinyl chloride polymer may be a homopolymer or a copolymer of at least 50% wt. vinyl chloride with a monoolefinic comonomer, e.g. the other vinyl halides; vinylidene halides; vinyl acetate, stearate or benzoate; acrylic acid and its derivatives such as methyl acrylate, acrylamide and acrylonitrile; vinyl aromatics such as styrene and chlorostyrene; and alkyl esters of maleic and fumaric acids.  The term "liquid polymer" refers to such polymers which are liquid at room temperature and have a polymerization degree between 8 and 20 according to ASTM D1243-58T.  Such liquid polymers may be prepared by polymerizing the monomer(s) in the presence of a chain transfer agent, such as halomethanes or thioglycol.  Any conventional polymerization process may be used in the invention, e.g. bulk, solution, suspension or emulsion.  Catalysts mentioned are benzoyl, lauryl and hydrogen peroxides; potassium and ammonium persulphates; azo-bis-isobutyronitrile; and dimethyl valeronitrile. Suitable suspension media are polyvinyl alcohol, methyl cellulose, gelatin, bentonite and talc; anionic or non-ionic surface active agents may be used as emulsifiers.  Examples illustrate the preparation of liquid polyvinyl chloride and vinyl chloride/acetate copolymer using carbon tetrachloride as chain stopper and the use thereof and of liquid copolymers of vinyl chloride with vinyl stearate or methyl acrylate in the polymerization of vinyl chloride alone and also with vinyl acetate (90%); vinyl stearate (10%); methyl acrylate (10%); and vinyl lauryl ether. n-Hexane was used as solvent in one example.  Stabilizers, e.g. dibutyl tin maleate; calcium, barium or cadmium stearate; white lead or litharge may be added before or after polymerization.
